Start tackling those spuds—your dairy-free cooking caper begins right here.

Lactose-Free Mashed Potatoes


Lactose-free mashed potatoes are just like regular mashed potatoes. The only difference is that they are made without any dairy products that have lactose in them. Lactose is a type of sugar found in milk and some people just happen to be unable to digest it. This is a case known as lactose intolerance

So, regular mashed potatoes can create digestive problems for lactose-intolerant people. That is why we are offering this recipe today, for which we are using lactose-free ingredients.

In place of dairy products, you can use almond milk or coconut milk. Both are good choices, and they give the mashed potatoes a rich taste.

For the famous creamy texture, you will want to use a dairy-free butter or spread instead of the regular dairy butter. There are many options out there, like vegetable-based spreads, vegan margarine, or an olive oil spread. Just like regular butter, they melt into the warm potatoes and create a smooth texture you cannot resist.

Some folks may prefer using vegan mayonnaise to add creaminess. So, next time you are at the shops, keep an eye out for plant-based butter substitutes. They are great in all lactose-free dishes, not just mashed potatoes.

Speaking of seasoning, salt, pepper, and garlic make a big difference, bringing out the taste of your mashed potatoes and helping replace the flavour missed from not using dairy products.

For a twist of flavour, you can try other herbs and spices too. Think about adding paprika, thyme or even onion. Many people also like to add rosemary, parsley, chives, dill or oregano for an extra kick. Soak cashews, then blend them in; this gives a smooth, creamy texture without milk or cream.

The goal is to make tasty lactose-free mashed potatoes, a recipe that is literally one-size-fits-all, so feel free to play with the ingredients and do not be afraid to get creative.

All right. Now that we know about the ingredients, how exactly can we make delicious lactose-free mashed potatoes?

Tips for Making the Best Lactose-Free Mashed Potatoes

While the recipe seems relatively easy and quick, taking a little over the time it takes the potatoes to cook and get tender, there are a few extra things you can do to achieve the best lactose-free mashed potatoes you can ever make. So, let’s look into that.

1. Choosing the Right Type of Potatoes

Potatoes are the star of this recipe. For the best lactose-free mashed potatoes, it is essential to choose the right type of potatoes. Both Russet potatoes and Yukon Golds are suitable choices. They both have a high starch content, which helps create a fluffy and creamy texture when mashed. They also hold their shape well during cooking.

So, whether you prefer the smoothness of Russet or the buttery flavour of Yukon Golds, either option will work great for your dairy-free mashed potatoes.

That said, red potatoes are often used as they mash up well and taste great, too. You can also try sweet potatoes for a change of flavour, texture, and colour.

2. Use a Potato Masher or Ricer

To achieve a smooth texture in your lactose-free mashed potatoes, it is important to use the right tools. A potato masher or ricer is highly recommended. These two tools help break down the cooked potatoes evenly, resulting in creamy and totally lump-free mashed potatoes.

While a potato ricer gives you the best results for a velvety texture, a food mill or hand masher can also work well. Remember that the tool you use will affect the final texture of your mashed potatoes, so choose wisely.

3. Adjusting the Consistency

For a perfect lactose-free mashed potato dish, consistency is key, and consistency highly depends on the milk content, meaning it can be easily adjusted by adding more or less milk.

It does not matter which type of non-dairy milk you are using, whether that is unsweetened almond milk, cashew milk, oat milk, or even rice milk. If you prefer a creamier texture, simply add a bit more milk to your mashed potatoes, or if you like them thicker and chunkier, use less milk. It is all about personal preference.

Variations and Additions

Besides these tips to get a creamier texture or a richer flavour, there are other ways to elevate your lactose-free mashed potatoes and enhance their flavour even more. Let’s see how you can achieve that.

1. Add Roasted Garlic for Extra Flavour

When making lactose-free mashed potatoes, one delicious addition to consider is roasted garlic.

Roasted garlic can add a rich and savoury flavour to your mashed potatoes. It brings a slightly sweet and caramelised taste, enhancing the overall depth and complexity of the dish. The garlic becomes milder and creamier when roasted, complementing the creamy texture of mashed potatoes and providing a deliciously comforting and aromatic element to the flavour profile.

2. Mix in Herbs or Spices for Different Tastes

To add more flavour to your lactose-free mashed potatoes, you can mix in herbs or spices. Fresh herbs like rosemary, thyme, and sage are great for infusing the vegan milk with additional flavours.

You can also experiment with other culinary herbs and spices to create different taste profiles. The aromatics from these ingredients will enhance the overall taste of your mashed potatoes without the need for dairy products.

3. Incorporate Dairy-Free Cheese for a Cheesy Twist

Adding dairy-free cheese to your mashed potatoes will give it a cheesy twist. It can impart a savoury and slightly tangy flavour to mashed potatoes, though the specific taste will depend on the type of dairy-free cheese used, such as a plant-based alternative made from nuts, soy, or other non-dairy ingredients.

Overall, it adds a cheesy umami note without the use of traditional dairy products. There are many options available, such as grated dairy-free cheese or vegan cream cheese, that can be mixed into the mashed potatoes.

Nutritional yeast is also often used as a dairy-free alternative to achieve that cheesy taste. 

Serving Suggestions

Lactose-free mashed potatoes are typically considered a side dish or snack rather than a main course. They often accompany a main course, such as grilled meat, roast chicken, or other protein-based dishes. However, in some instances, they can serve as a component of a vegetarian or plant-based main course, especially when combined with other hearty ingredients to create a more substantial dish.

Let’s explore a few different ways to serve your delicious lactose-free mashed potatoes.

1. Pair With a Dairy-Free Gravy or Sauce

To complement the creamy and flavourful lactose-free mashed potatoes, consider pairing them with a delicious dairy-free gravy or sauce. This adds an extra layer of taste that will delight your taste buds.

You can choose from a variety of options, such as mushroom gravy, onion gravy, or even a tangy tomato-based sauce. If you prefer convenience, you can use store-bought jarred gravies or gravy mixes, though be cautious, as some may contain high FODMAP ingredients like lactose.

2. Enjoy as a Side Dish With Your Favourite Protein

As a side dish, lactose-free mashed potatoes can be served with any kind of protein-based main course, such as a delicious meat or fish dish. Whether you are enjoying a juicy steak, tender chicken, or tasty salmon, these creamy and smooth mashed potatoes enhance the flavours and provide a comforting balance.

They are so versatile that you can pair them with a variety of plant-based protein dishes such as beans or tofu, making every meal even more enjoyable. 

3. Use as a Base for Other Dishes

One of the great things about lactose-free mashed potatoes is that they can be used as a base for other delicious dishes.

For example, you can use them as a topping for shepherd’s pie, giving it a creamy and flavourful twist. If you have some leftover mashed potatoes, you can turn them into vegan potato pancakes, making a tasty breakfast option. You can try making Irish boxty, which is a traditional recipe for potato pancakes using lactose-free mashed potatoes.

The possibilities are endless when it comes to using these versatile dairy-free mashed potatoes.

Storing and Reheating 

To ensure the freshness of your lactose-free mashed potatoes, store them in an airtight container in the refrigerator for up to four days. If you have more than you can consume within that time frame, freezing is an option. To freeze your dairy-free mashed potatoes, use a plastic container suitable for freezing and store them for up to two to three months.

When you are ready to enjoy them again, simply thaw the frozen mashed potatoes by transferring them from the freezer to the refrigerator until defrosted. When it is time to reheat, simply transfer the desired portion to a microwave-safe dish and add a splash of liquid, like milk or cream, to help keep them moist. Then, heat them in short intervals for 1-2 minutes, stirring every 30 seconds to ensure even heating and prevent any overcooking.

Alternatively, you can use the stove to reheat your lactose-free mashed potatoes. Add the desired portion to a saucepan placed over low heat and stir frequently until the potatoes are warmed through. Remember to add a splash of lactose-free milk if needed to maintain that creamy texture. This method allows for more control over the temperature and helps maintain their creamy consistency. 

Whichever method you choose, be careful not to overcook or dry out the potatoes, as this can make them lose their smooth texture.


This lactose-free mashed potato recipe is a delicious and creamy alternative for anyone who cannot have dairy. With simple substitutions like using almond milk or dairy-free butter, you can enjoy the same great taste without any discomfort.

Whether you are lactose intolerant, following a vegan diet, or just looking for a healthier option, these mashed potatoes are sure to be a hit at your next meal. Give them a try and see how easy it is to make everyone happy.
